Crossed Roller Slide Tables are factory assembled, and ready to install. They use Del-Tron crossed roller bearings to provide very precise linear motion with low friction and high support stiffness for the load. A selection of more than 50 standard sizes is available for applications including precision instruments, office and communications equipment, surface grinders, tool grinders, assembly fixtures, and anywhere precise linear positioning is required.

Construction
Each positioning table consists of a one piece base, a one piece carriage, and a pair of linear bearings. The bearings are factory preloaded to eliminate side play.

Counterbored clearance holes in the base permit easy mounting in your structure. Threaded holes in the carriage are closely spaced to permit attaching your components without additional machining in most cases.

Standard material for base and carriage is cold rolled steel, with black oxide finish.

Application
Mount on a flat surface to provide full support to the base.

Although it is seldom needed, the carriage surface can be machined or additional mounting holes can be added if the following precautions are observed:

1. Do not disassemble the table since reassembly and readjustment of the preloading require special procedures.

2. Protect the ways against entry of chips and debris.

3. Drill only blind holes through the carriage to avoid depositing chips inside the unit.

4. Avoid intersection with internal mounting or preloading screws.

5. Avoid clamping forces in excess of the rated load capacity.

Internal stops, in the form of projecting screw heads between the under side of the carriage and the base, are intended only to protect the bearings from overtravel during handling. Provide separate stops appropriate for your load if needed.

The ends of the carriage contain tapped holes that permit easy attachment of way covers, bellows, or other shields to exclude dust and keep the ways clean.
